Yummy! A few modifications I changed, fitting to what several other people suggested, I also ran out of walnuts, so subbed it out as well:
1 Cup of Oil => 1/2 Cup Oil + 1/2 Cup Orange Juice
Orange Zest => Fresh Lemon Zest (2 Lemons = 1 TBSP)
Walnuts => Cranberries (Craisins, Dried Cranberries)
It tasted SUPER Good! Makes a fantastic bread for sitting out on the porch in the evening with a cool glass of sun tea snacking away!
